The collection will be auctioned at Noonans in Mayfair on 4 March as part of a coins and historical medals, external sale.
Alice Cullen, coin specialist at Noonans, said the hoard fits the pattern for burials -being found on the east-facing side of a hill.
Licence believes the “morning sun illuminating the hillcrest and a spring rising at the same spot” is a combination that could point to this hoard, and others like it, having a religious significance.
Among the highlights of the hoard are the Addedomaros wheel stater, which confirms the spelling of the name on that early type, which was previously uncertain. It is estimated to fetch £3,000-3,600.
The Dubnovellaunos stater, with a previously unrecorded die, is expected to fetch £1,500-2,000.
